High Temperature Composite Seal Seat
Designed for boiler soot blowers, this seal seat addresses extreme temperature conditions at the furnace entry point. Traditional seals often burn out, causing smoke and air leakage. Our multi-layer composite design solves this problem: a heat-resistant base, flexible seal layer, and wear-resistant bushing work together. The split installation design with stepped positioning ensures precise fit and easy maintenance.

Key Advantages
1. Prevents Smoke Leakage from Boiler Walls
Designed for boiler soot blowers, this seal seat addresses extreme temperature conditions at the furnace entry point. Traditional seals often burn out, causing smoke and air leakage. Our multi-layer composite design solves this problem: a heat-resistant base, flexible seal layer, and wear-resistant bushing work together. The split installation design with stepped positioning ensures precise fit and easy maintenance.
2. Withstands Extreme Furnace Heat
The seal seat operates reliably at temperatures up to 850°C. The base is made of heat-resistant cast steel or superalloy, while the composite layer uses flexible ceramic fiber and high-temperature graphite. This allows both long retractable and fixed rotary soot blowers to move freely without sticking or degradation.
3. Near-Zero Leakage Improves Work Environment
The near-zero leakage rate effectively stops flue gas escape, improving on-site working conditions and worker safety. We hold occupational health and safety management certification, and we can customize the seal seat for different lance tube sizes. The inner diameter fit tolerance is H7/h6, with a wear life of ≥8,000 hours.
FAQ
- Can it fit different lance tube sizes? Yes, inner diameter tolerance H7/h6.
